Birth defects of teenage pregnancy,how soon can i take pregnancy test after ivf,pregnancy chances low amh treatment - Review

Birth defects are structural or functional abnormalities present at birth that cause physical or mental disability. We sometimes say that two people are so close that they appear ‘joined at the hip’ –metaphorically speaking, of course.
Approximately half are stillborn, and a smaller fraction of pairs born alive have abnormalities incompatible with life. The excess growth of hair occurs in areas of the skin with the exception of androgen-dependent hair of the pubic area, face, and auxiliary regions. Facial dimorphisms, tooth abnormalities, hex dactyl and accessory nipples have been reported in single cases. Sirenomelia, alternatively known as Mermaid Syndrome, is a very rare congenital deformity in which the legs are fused together, giving them the appearance of a mermaid’s tail. More than half the cases of sirenomelia result in stillbirth and this condition is 100 times more likely to occur in identical twins than in single births or fraternal twins. It results from a failure of normal vascular supply from the lower aorta in utero.
Cyclopia is a rare form of holoprosencephaly  and is a congenital disorder (birth defect) characterized by the failure of the embryonic prosencephalon  to properly divide the orbits of the eye into two cavities.
Craniopagus parasiticus is a medical condition in which a parasitic twin head with an undeveloped (or underdeveloped) body is attached to the head of a developed twin. Fetus in fetu is a developmental abnormality in which a mass of tissue resembling a fetus forms inside the body. Fibrodysplasia ossificans progressiva (FOP), sometimes referred to as Stone Man Syndrome, is an extremely rare disease of the connective tissue.
Progeria  is an extremely rare genetic condition wherein symptoms resembling aspects of aging are manifested at an early age. Those born with progeria typically live to their mid teens and early twenties. It is a genetic condition that occurs as a new mutation , and is rarely inherited. In the context of human evolution, human vestigiality involves those characters (such as organs or behaviors) occurring in the human species that are considered vestigial—in other words having lost all or most of their original function through evolution. In some cases, structures once identified as vestigal simply had an unrecognized function.Vestigial characteristics occur throughout nature, one example being the vestigial hind limbs of whales and snakes.

Anencephaly is a cephalic disorder that results from a neural tube defect that occurs when the cephalic (head) end of the neural tube fails to close, usually between the 23rd and 26th day of pregnancy, resulting in the absence of a major portion of the brain, skull, and scalp. By puberty, male germ cells go through around 150 cell divisions, compared to the 22 cell divisions experienced by female oocytes (immature egg cells).

A rare phenomenon, the occurrence is estimated to range from 1 in 50,000 births to 1 in 100,000 births, with a somewhat higher incidence in Southwest Asia and Africa. The whole body of patients with Ambras syndrome is covered with silky, lightly colour  hair that can reach several centimetres in length and is most prominent on the face, ears and shoulders. Unlike other forms of hypertrichosis, none of the patients with Ambras syndrome had metabolic or endocrine defects. This condition is found in approximately one out of every 100,000 live births (about as rare as conjoined twins) and is usually fatal within a day or two of birth because of complications associated with abnormal kidney and urinary bladder development and function.
Maternal diabetes has been associated with caudal regression syndrome and sirenomelia, although a few sources question this association.
Its incidence is 1 in 16,000 in born animals, and 1 in 250 in embryos, one in 2,500 that end in miscarriage.
A mutation of the body’s repair mechanism causes fibrous tissue (including muscle, tendon, and ligament) to be ossified when damaged. Although the term progeria applies strictly speaking to all diseases characterized by premature aging symptoms, and is often used as such, it is often applied specifically in reference to Hutchinson-Gilford Progeria Syndrome.
Most babies with this genetic disorder do not survive birth, however there have been notable exceptions.
Siamese twins are formed from a single egg which develops into two almost separate balls of cells.
The end results can be very bizarre:  a single organism with two heads, two hearts, four legs and arms.
Typically, the face is either missing or replaced with a non-functioning nose in the form of a proboscis.

One theory is that the mass begins as a normal fetus but becomes enveloped inside its twin. A fetus in fetu can be considered alive, but only in the sense that its component tissues have not yet died or been eliminated. The disorder has very low incidences and occurs in an estimated 1 per 8 million live births. Currently, birth defects are the leading cause of death for infants during the first year of life. Such a proboscis generally appears above the central eye, or on the back, and is characteristic of a form of cyclopia called rhinencephaly orrhinocephaly. There is a missing nose or a nose in the form of a proboscis (a tubular appendage) located above the eye. Thus, the life of a fetus in fetu is akin to that of a tumor in that its cells remain viable by way of normal metabolic activity.
As a result cells in Siamese twins become confused about where they are in the body – indeed which of the two Siamese twins they are actually in.
A child with FOP will typically develop bones starting at the neck, then on the shoulders, arms, chest area and finally on the feet.
